VENEER-DISH MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,822, dated January 2, 1883. Application filed March 20, 1882. (N0 model.)

To all whom it may concern.-

Be it known that I, RILEY BOWERS, aresident of Indianapolis, in the county of 'Marionand State ofIndi-ana, have invented a new and useful Improvement in Veneer-Dish Machines, of which the following is a specification, having reference to the accompanying drawings.

My invention relates to an improved form- 'ing-block in veneer-dish machines, a devicefor under the folding apparatus, and a clinching mechanism contained within said block, as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure l is afrontelevation, the folding device being shown in section. Fig. 2 is a side elevation of the forming-block and its connections, the block and hollow shaft on which it is mounted being shown in section. Fig. 3 is a rear view of the same.

Like letters refer to like parts in all figures.

a is the frame-work of the machine.

I) I) represent the staple forming and driving mechanism; well known in this class of machines.

c is the forming-block, having four formingfaces. Said block is secured to one end of the hollow shaft on, which is mounted to revolve in suitable hearings in the framea. A tappet-wheeLf, having-four arms, is also secured to shaft m. An intermittent motion is given to the forming-block c by an arm, y, secured to the driving-shaft t, striking and carrying forward at each revolution one of the arms on tappet;w11eel f. Each forming-face c is provided with pairs of sliding pins 0 6, moving easily in radial holes bored in said faces, in such a position as to come opposite the ends of the staples holding the dish together as they are driven through the dish when formed by the staple forming and driving mechanism b. The innerends of said pins 6 rest on a cam, (1, within a recess in the side of the formingblock. Their length is such that when they rest on the portions of the cam farthest from the center they project slightly above the surface of the forming-faces; but when said forming-face is in position for receiving the blank to form a dish their inner ends rest in de-' pressions in said cam, and their outer ends are about one-fourth of an inch below the surface of the block. (Jam dis secured to a shaft, 1, passing through and turning within shaft m. An arm, h, is secured to the other end of said shaft 1", and the cam is partially revolved by arm j on the driving-shaft coming in contact asit revolves with arm h, which is drawn back into its former positiouby spring a as soon as armj has passed.

A folding device, 6, of well-known form and construction, is secured to upright bar a, which is moved intermittently up and down by mechanism not. shown here. In addition to the usual side and end forming and folding parts of this device I provide the plungers 0 0, which are mounted on and move vertically within the ends of the folding form, as shown. They are provided with spiral springsm, which yield as the folder moves downward after the plun gets 0 bring the central portions of the ends of the blank dish in contact \viththe formingblo'ck 0 below. As the folder moves downward the plungcrs come first in contact with the ends of the blank and press them down, and as the folder comes farther'down hold them with a yielding pressure till the sides are also pressed down. In this class of folding devices as heretofore made the ends and sides of the dish are pressed down simultaneously, thereby frequently causing the dish to crack at the bottom corners. By folding the ends down first this is avoided.

The operation of my machine is as follows: A dish-blank of veneer having been placed on the upper forming-face 0, the folding device is moved downward and folds it into form, as above described. The staples are then driven through the ends of the dish by the staple forming and driving mechanism 1), the ends of the staples passing through the dish and projecting into the holes in the former, in which ins 0 slide. .Vhile the staple-drivers are still in position against the driven staple, armj on the driving-shaft comes in contact with arm II, and turns the cam (I, thus forcing the pins 0 outward and clinching the ends of the staples. As soon as arm j has passed, cam (l resumes its former position, as before described. The folder now moves upward to its former position, the stapledrivers reecde, and arm 9 comes in contact with tappet-wheel f, and thereby turns the former-block over one-quarter of a revolution, carrying the dish with it and presenting a new forming-face. As the formerhlock is further revolved the dish falls off be- 3 low.

I claim as my invention- 1. In a veneer-dish machine, the combination, with the forming-block c, hollow shaft m, and pins 0, of the cam d,shaft 1', arm h, spring 1;, and revolving arm j, for the purpose set forth.

2. In a veneer-dish machine, in combination with anintermittently-revolvingforming-hlock having two or more forming-faces, as described, a staple-clinching device consisting of the longitudinally-reciprocating pins 6, moving in holes in said bloclgand a mechanism,substantially as described, for forcing said pins out Ward against the staple-drivers, as set forth.
